[Qemu-devel] [PULL 6/8] migration: Reset rather than destroy main_thread_load_event

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

migration_incoming_state_destroy doesn't really destroy, it cleans up.
After a loadvm it's called, but the loadvm command can be run twice,
and so destroying an init-once mutex breaks on the second loadvm.
